Answer 1

Question : Why do we itch. Why do we react the way we do?

i would say that we would like to remove the irritant as possible and once you have scratched the area of irritation and your likely going to find some relief with your finger nail scratched away the irritant then it gets sent to your brain saying it gone and your all good.

Hopefully that helps you ! have a good day !

Answer 2

The skin feels a certain sensation from outside influences. The same thing that itches also detects hot, cold and sensations of other kinds. The technical term for it is stimulation of pruriceptors. When these pruriceptors are stimulated, the brain reacts with an appropriate response.
